Domestic Well Owner Resources

Maintaining your domestic well
1. Have your well sounded
This will require hiring a contractor. This method will give you an accurate groundwater depth at your exact well location.
2. Have your water quality tested
Fresno County
Free water quality sampling of Bacteriological, Nitrate, and in some cases DBCP is available to well owners as a part of their permit fee. If you have not previously received your free sampling, contact Fresno County to make arrangements at (559) 600-3357 and ask to speak with the water specialist. Sampling for any other constituents requires hiring a contractor.
Kings Water Alliance
If you live in MAGSA and your household water comes from a well, you may be eligible for a free well test to test for unsafe nitrate contamination. The Kings Water Alliance is a local non-profit that will test your well and provide bottled water delivery to your home at no cost if your well is found to have unsafe levels of nitrate. Learn more, and find if you are eligible by filling out their 2-minute survey here.
3. Contact MAGSA for latest readings at monitoring wells in the area
Although it may not be as accurate as a measurement taken at the exact well site, monitoring wells represent the general groundwater conditions within your vicinity.
4. Understand signs that indicate your well is vulnerable to going dry
- You notice sputtering air pockets when you are running water.
- There is sand or sediment in the water.
- The water is not clear, but muddy.
- Water tastes or smells funny.

- Neighbors report same problems.
Call MAGSA at (559) 515-3339 or send us an email at info@mcmullinarea.org if you are concerned your well is vulnerable to going dry.
